LOCK-NUT.

1,277,423. Specification of Letters Patent. Patented Sept. 3, 19 8 Application filed September 26, 1914. Serial No. 863,722.

To all whom it may concern:

Be it known that I, Mounts Jacons, a

citizen of the United States, and resident of the town of Middletown, county of Qrange, and State of New York, have. invented certain new and useful Improvements in Lock- Nuts, of which the following is a specificatlon.

Although much has been done by myself and others in this art, the art itself is so important that the greatest pbssuble -advancement and each and every new and" loriginal feature 1s desirable.

I have endeavored to cheapen the cost of manufacture'and simplify the operation of the device without in an way detracting or subtracting from its e ciency and useful- .The construction and mode of operation of this: my latest invention in this art will be fully developed and described asthe specification progresses.

The following is what I consider the best neans of carrying out this invention.

The accom anying drawings form a part vf this specit ication in which:

Figure 1 shows in plana nut provided vith releasing and additional loclgingmeans. Fig.1 is a sectional view of a nut showing means for securing the locking member herein.

Fig, 2 is an elevation of the device shown 1 Fig. l and shows the means for securing ieonter end of the locking spear.

'Fig. 2 is in side elevation partly in sec on and shows another view of the outer or :cured end of the locking spear. Fig. 3 shows a locking member and a nut fovided with a single perforation through hieh the additional locking or releasing eans may operate.

Fig. 4. shows another means for securing e outer endof the locking spear. Fig. 5 shows a locking member of somenit different shape and having certain finite advantages. Fig. 6 is a side elevation of the locking ear shown in Fig. Fig 7 shows a duplex lockim spear lock 5 the nut and bolt against re ative motion either direction. in. 7 shows in side ebwation a nl'it eroin the releasing means is arranged at angle.

Fig. 8 shows in elevation a nut into which is inserted the spear operating means.

Fig. 9 shows in plan another locking spear having definite advantages.

Fig. 10 shows another means for securing the locking spear into the nut.

Fig. 11 shows a slightly different means for obtaining a tension in the locking spear.

Fig. l'2shows in elevation partly in section, a means for securing and ietalning the tensional locking men'iber.

Fig. 13 shows an additionalmeans for securing the tensional locking spear. Fig. 14 showson a large scale, the relative length of the locking spear before and after the torsional twist has been applied.

Fig. 15 shows on a larger scale a nut having a. modified recess.

Figs. 16, 17 and 18 show modifiedmeans for holding the spear in the nut.

Figs. 1!) and 20 show in diagram the approxin'iate alinement of recesses to obtaur the desired results.

Similar reference numerals indicate like parts in all the figures where they appear. a

At 1, I have shown a nutand in the Figs. 1 to 4 inclusive 1 will indicate as l, a common ordinary nut produred by any well known moans. At 2 the boll. is shown and this is an ordinary bolt of any length'and adapted to fit the nut in the ordinary manner. At the inner face of the nut l, I produce a recess 3,- which may be of any desirable outline but it must connect with the bore in the nut into which the bolt enters, and it must be of sufiiricnt size to allow my spear thrustlocking member to operate uurestrained except to the extent that l have found necessary and desirable and will fully describe.

Parallel with the central screw-threaded perforation but spaced certain distances therefrom, I produce a plurality of perforations 4, 5, and 6', and into the perforation 6, I pass a member that has been produced of hard dra'wn. steel wire or of any other similar substance. this,

Before insertin wire member I cause a right angle bigd to be produced therein which will for the locking spear 7, and I may shar nm or reduee the outermost end of this ice ing spear as shown at El. The; recess 3, is of a depth about equal to one screw-thread, and the wire member is of a diameter that'will not allow 7 to bo tirmlyimpingod upon tho wall 11' the body of tho spear 7 to projcct upward abovo lhc face. oi the nut 1. The spcar 7 must howcvcr. hoof -uliiciont length to allow the ond f8 t'o projcclt lo-a ccrta in extent into the Unit. riaiciving pc'rt'oration'of thc. not. i

Tho IOtilllllg' of tho wire, or nut. produces a torsional twist of the wire in the out for a purpose that shall appear latcr.

The drawings. i di a t I a nut of any ordinary shapeorsize or even lbb' 1a spncia-lnutmay'ho utilized with any of my devices. H

In Figs. and 6,'I have shown'a tensio'nal locking spear of somewhat different outline and in the nut shown-in Fig. 5 I have produccd a. rccess shaped to-recei've' this I particular locking spear. The locking spear consists of the spcarcnil 21 projecting into.

the scrcw-tlireadcd perforation of the nutQ-f 1' Tho spring or tcns'ional lnombcr is bcntintoi .110 a partial loop as shown at 22 and 'into la smaller nearly complete loop as shown at 23. The inner cnd'Qiisflattened as-shoivn at25 and-is forced downward into n Shal'-,. low perforation. 'The"forcing"- of the flat; tcncd portion into a shallow pcrforation' may in! .dcpended .upon for sccurin the whole 'tcnsioim'l locking member or may forcethe wall of one of the sides of the nut fie 26 in Fig. 10 displacingfthccnd or projectionby forcing it out of alinon'ient. An-

other moans for securing tlfc tensional look ing member 22 may be utilized, and this means is the caving of one of the walls of. the'rccess as shown at, 27.

In this Fig.5,- I have shown a releasing perforation and a sccond perforation 29 which may assist in rcinforcing the looking cngagcmcnt by forcing tho spear QITarther 1'30 cation is present to a certain extent in all ofmy devices here; it is enlarged upon in the following manners-2 Before being inserted into the recess the resilient member being of a. length greater than the interior of the. recess therefor, the locking member must lie-forcibly Inserted into the recess. When wear occurs the lockin member confined by the walls of th W1 l advance longitudinally pl'ojectinlg its 16 tongue at all times to a certain desirab e extent into the screw-threaded perforation.

At Fig. 7, I showa means for preventing rotationkof the nut or bolt in either direc- "tion. This .means com rises two locking! 20 spears and 3-1 arrangta at an angle to each other and to the bolt. Each of these spears is "operable in themanner fully described in relation to the other locks and each is releasable through a perforation 32 and 33 25 respectively,

perforations 3.4 and 35 1501 reinforci x ig the locks and perforations 36 and 37 for" securing their respective ends of the spear agalnst the possibility of releasing the bolt. '1 have 30 shown 'anail or similar instrmncnt in each of the perforations 36 and 37 but because of the nature of this particular securing means these perforations 36 and 37 may be omitted. The ,wire member 38 is in this in- 3 stancea.bow, both ends of which are inwardly projecting and I secure this wire member by means of the impressed or upset wall 39 of the nut.

In Fig. 8,'I have shown two ordinary nails 40 used for releasin'g or further securing the securing-means and as it may sometimes be desirable to-allow a n'ail to remainin position for an indefinite cried I may countersink the outer faceol the nut as indicated at 40 allowingthe head of a short nail to pass. into the countersink and to. be concealed under the outer face of the nut. I

. may. also provide a. channel 41 for the .inser-' tlon of anothergtoolfor rcmovingl-the .nail.

"In'Fig. 9, ;Il1ave shown a construction as important her and yet somewhat different in ope tion. Here the recess proper is compose d nfa plurality of recesses 43 and it which' produce the projections 45 and 46 opposite each other and a further projcction 47 at the edge oftlie screw-threaded perforation.,Theiopking member here em ployednsof somewhat difi'e'rent shape than those thus far shown and described and it is.

forcibly held betweenthe projections 45 and 46 and causedto firmly impinge upon the projection 47L fIhe -outcrend-of this locking member is tm'nedap rOXimateIy at right angles as shown at 48 and passes through a 85 groove or channel*4 9 to the outer side wall I have provided additional;

of the nut. Here a saw-kerf may be produced into which the. end 48 of the locking memht r may be forced, after which the wall of the saw-kerf may be upset in the same nnnneras shown in Fig. 4. a

I desire it understood that in all of the .dmflelopmcrits of my inv-cntion the locking spear is.. under all conditions a tension mcinher and that even when the bolt is not in place. the locking spear is forciblycngaged againstthe wall of the recess. Although the bolt will remove the spear from thewall of the recess the removal of the bolt and the 1'e leasing nail or instrumcntwill allow the locking spear to return into firm engagement with the wall of the recess.

In Fig. 11, I show a construction some what similar to Fig. 9. though in this instance, I have provided two rewsscs and a single perforation for operating thc locking spear; The use of this single perforation 50 is fully described in connection with the polforation 17 inl ig. 3, and in this Fig. 11. the same refm'cnceletters are used to indicate the different sides of the lockina s 'iear. In the smaller recessfil, I produce an additional perforation which h'iay 01 may not extend quite through the nut and into this additional perforation, I pass the end of the torsional member. The larger recess 53, provides freedo/i orthemotion of the lock- 1n"g "-spcar and l 'in'the-spar/is obtained by confining the shaft thereo f between the shoulders 54 and and causingit to strongly impinge upon the shoulder 56. J

In Fig. 12, I show one of themeans that I have utilized for securing the torsional member. The stem is here shown as passing through a perforation 57 that extends almost Wholly,through thehut and which is inter sectedby a saw-kerf} 58 into which the outer [a vise or suitablcftool and then turning the put one full revolution before the end 59 is' --depresse l into the sawkerf. This willh'ave a tendency to shorten the-torsional member as shown in Fig. 14. and a movement of this member evento a small extent in the directionto nntwlst or relieve the torsional Stlillll,

will tend to lengthen the member allowinf it to compensate for wear of the spear en is "positive tension desirable I In Fig. 13, I show another means for se-' curing the torsional member. Here the perforation 60 extends but part way through the nut. and when the end 61 is dropped into this perforation, a suitable tool is caused to force inWa-rdthe side of thenut as shown at 62 forcing the. metal thereof.

firmlyagainst the stern of the torsionalnnemtion as shown at; 72 and 73. foration 73 I insert the end ofa locking'spcar and l secure lttherein by forc ng'inwardher and forcing the torsional member to a greater or less extent out of alinement.

In. Fig. 15 I have shown on a large scale a nut provided with two recesses 70 and 71 which together forn'l the dc. red recess and in each of the recesses I produce a. perfora.

the wall of the nut at 74. The outer end of the locking spear passes over the perforaed extent.

tion 72 and enters the bolt hole 75 to a limit- A nail or other tool may be inserted into the perforation 72 for locking the locking spear.

' It-.will be observed that the arrangement.-

aud location of the recesses 70 and 71 prothe body thereof will be caused to hear more firmly .upon the abutment 76, when z.li(' we\'cr the bolt and releasing means are withdrawn the spear will return to bear --li r|nly upon the abutment 77 as shown.

In Fig. 1] l show in elevation a spear formcdas described in cmmectirm with Fig. 15 and I'Uttll'l'lfitl by caving. or forcing inward the wall of the nut.

.In l ig. 1H 1 show another way of securing the end of the spear. "This consists of bending the end at right angles continuing it through the counterbore 71 and then bending' it once more at right angles and pro-' 'jecting the end through a-saav kerf inthe wall of .tliecounterbore. The. end may be upset outside .of the/nut as indicated ,at St or I may spot-weld the end of the nut.

the back or. shoulder thereof is forced against the adjacent wall of the recess and instead of the spear accepting all of the strain of the locking,,thc nut itself takes a greater portion of the strain allowing me to use a spear of lighter construction than would otherwise be required and obtaining for me a strong lockin r The nut itself ma be made a commercial product with the dltferent holes and countor-bores produced therein as described. The tension springs may be supplied as separate members to be inserted into the nut by the purchaser and at any subsequent period. No mechanical knowledge is necessary in placing the tcnsional members or in assembling the lock into the nut and when assembled even by one not familiar with mechanical devices it will be found that the complete device will contain all of the features present were the device assembled by an expert mechanic. The same permanent and tensional locking features will be present and the same compensating in length for wear and the same reinforcing of the locking member by the wall of the nut.

It obvious thatcertain parts of one device here shown may be used with anotheror that certain parts of any may be omitted with the loss of its function. I have de scribed a device so simple in its construction that it may be produced at an extremely low cost; a cost that I have estimated to be about one fourth of a cent. I may fur ther cheapen the construction by providing the die which is used for blanking out the nuts with a plurality of projections so shaped that they will produce in the inner face of the nutthe necessary recesses, shoulders and abutments at the time that the nut is blanked out.

Another improvement is that shown in Fig. 7. wherein the perforation for the insertion of the releasmg' nail is arranged at an angle so that when thenail is inserted it will hold the wire spear member in a releasable condition Without requiring that the point ofthe nail shall project above the surface of the nut. Its angle may be that shown by the dotted lines w. While I do not claim a crforation or a lurality ofrecesses as Invention I do believe that the location of abutments and shoulders in such a manner that they will create and retain a tension upon. a scar member as and in the manner set fort is an invention of the highest order.

And as the construction that I have herein shown and described performs few and important functions and asa nut containing abutments for thepurposeherein shown is new I therefore believe the nut alone one of the most'imp'ortant features of my invention. Thenew and special. lock held by these abutmcnts is so held that the opera said recesses and means for insuring or protion oil. the bolt can not carry the lock to a ducing a permanent tension to said torposition beyond which it is practicable for sional member as hereinispecified and for all urposes.
